IMPROVEMENT IN WOOD-SAWING MACHINES.

Specilication forming part of Letters Patent No. 135,216, dated January28, 1873.

To all whom it may concern.-

Be it known that I, SAMUEL FUNCK, of Quincy, Illinois, have made andinvented a new and useful Improvement in Wood-Sawin g Machines, of whichthe following is a specitication:

N alture and Objects of the Invention..

My invention has relation to an improved machine for sawing wood; andconsists ot' an open frame, at the top ot' one side ot' which, attachedto two uprights, is secured a horizontal beam, below which the sawingapparatus is placed. An ordinary saw is fastened in any convenientmanner at either end to metallic slides that work in grooves attached tothe two upright pieces of a frame, the top piece of which is horizontal.To the lower ends of the `vertical pieces last-aforesaid rollers aresecured, upon which the saw-frame rests-two or more guide-rods on eitherside, which pass through the adjacent uprights of the principal frame,assisting in holding it in place as well as in giving it, when inmotion, a true direction.

To the slides to which the ends of the saw are fastened either` end of ametallic rod is attached, which, bent in rectangular form, extendsupward above the top of the saw-frame. At its corners cords arefastened, which are secured to a windlass, by means of which thesaw-frame may be elevated. Securely fastened to the rear side of thesaw-frame is a pivot, upon which a pitman works that, connected withgearings and a crank, actuates the sawing mechanism.

Description of the Accompanying Drawing.

General Description.

that passes through the uprights c a and top piece a. C is the saw,which is of the usual crosscut form, either end of which is secured tothe bolts D that pass throughA the ears E upon theI slides F. The slidesF are'constructed so as to admit of their being raised or lowered withinthe vertical beds G, which are fastenedto theupright pieces, their sidesbeing carried beyond the edges of the slide to prevent it from beingdislocated. (See Fig. l.) Ri gidl y fixed in the saw-frame are thehorizontal guide-rods'H, which pass through the up- I'ights a a, and aremade of suiiicient length to permit the necessary movement ofthesawfra1ne.\ ,Turning within slots cut in the verticalpieces of thesaw-frame are the rollers I, upon which the frame rests, and which serveto facilitate its operation. At a convenient point upon the rear side ofthe horizontal piece b the pivot or piu K is attached, and working uponit is one end of the pitmaii L, the other end of which turns upon thepivot or pin M uponthe wheel N, which is rigidly secured to the axle O.A gear-wheel, P, at a point upon the axle O toward the rear, is operatedby a gear-wheel, R, upon the axle S that is provided with a crank, T,being placed in a convenient position to eiect its purposes. Upon thehorizontal top piece a a windlass, V, which is ot' the usual form, isplaced, the crank U exten ding toward the rear, two grooves being cut inthat portion which extends beyond the front of the frame. vCords U arefastened so as to roll in either of the grooves, passing over rollersattached to the piece A, as shown in Fig. 2. The cords U are fastened tothe rod V, which is attached to the slides F, being bent upward in arectangular or other convenient form. A pin, W, may be used to hold thecrank U in place, a .hole being cut to receive it.

Operation.

The wood to be'sawed being placed in position below the saw, the crank Tis turned, when motion is communicated to the sawframe, moving it fromside to side; it being desired to raise the saw, thel crank U is turned,when it is drawn upward'at pleasure. The pin W being applied, the sawremains suspended.

' Claim.

Having thus described my invention, what I claim as new and useful, anddesire to secure by Letters Patent, is

The saw-frame B, consisting of two vertical In testimony that l claimthe foregoing improvement in machines for sawing wood, as abovedescribed, I have hereunto set my hand and one horizontal pieces,provided with the and seal this 5th day of October, 1872. guide-rods H,rollers I, vertical slide-beds G,
